introduction

Thank you for purchasing an a/d/s/ L series mini-speaker system. The L210 and L310 are the latest

descendants of the original ADS mini-speaker which first introduced the concept of big sound from a

small box. The L210 and L310 produce superior sound with classic a/d/s/ drivers and advanced crossover

technology. The sonic realism, bass response, and output capabilities are remarkable for such compact

loudspeakers. The L210 and L310 are magnetically shielded and are supplied with mounting brackets.

This edition of a/d/s/ mini-speakers features new cast aluminum housings that are weather resistant,

allowing the L210 and the L310 to be permanently mounted outdoors. In addition, the L210 and L310

drivers are magnetically shielded so that they may be used indoors near television screens or computer

monitors. The L series mini-speaker systems will not only provide excellent performance when used

alone, but may also be combined with an a/d/s/ powered subwoofer to provide stunning full range high

output Audio/Video system performance. Clearly the L210 and L310 are two of the most versatile

speakers available. Any type of system, ranging from outdoor applications, to home theater systems,

to multimedia computers can take advantage of their exceptional performance.

Installing the L210 or L310 is not difficult. However, correct wiring and proper placement play a vital

role in optimizing sound quality. This manual provides information on the placement, connection and

operation of your loudspeakers. Please read it thoroughly and save it for future reference.

speaker placement

Where speakers are placed significantly affects their sound. Some general placement guidelines are

given below. However, since all situations are different you should experiment with various locations

to determine where they sound best.

Outdoor use

Although the L210 and L310 are “all weather” loudspeakers, when using them outdoors you will

extend their life and improve reliability if you avoid mounting them where they will be exposed to

direct sunlight for extended periods of time. The L210 and L310 will stand up to moderate amounts of

moisture. However, they should not be mounted will be directly exposed to heavy rain. In colder

climates, bringing your loudspeakers inside for the winter when they are not being used is advised.

Boundaries

In general, the L210 and L310 will produce the smoothest response and best stereo image when located

at least two feet from the room boundaries - that is, the floor, ceiling and walls. Moving the speaker

closer to one or more boundaries will increase the bass output. In some rooms, the extra bass will

enhance the sound. In others the extra bass will be too much, making the sound “boomy” or “tubby”.

Experimenting with speaker placement is the most important thing you can do to achieve the best

possible sound.

“Hard” surfaces near a speaker can affect the distribution of high frequency sound in the room. As a

result, the accuracy of the stereo image. If the speakers are near the corners, point the speakers

towards the center of the room. If the floor in front of the speakers is not carpeted, place a small area

rug in front of the speaker to reduce high frequency reflections and improve the stereo image. When

a speaker is on a shelf or tabletop, keep the front of the speaker flush with the edge of the supporting

surface if possible.

Height

Try to place the speakers so they are close to the same height as your ears when you are seated in the

preferred listening area. Also be sure the speakers are high enough that the sound they produce will

not be constrained by

Separation

Start at your preferred listening position with the speakers at the points of an equilateral triangle, aimed

toward the listening position. (See diagram.) Experiment with moving the speakers closer together and

varying the aiming angle until you get the stereo image you prefer.

Speaker orientation

Stereo imaging is generally best when a speaker’s long axis is vertical, but horizontal placement is by

no means ruled out. Try the speakers both ways to determine if the difference in sound is important

to you.

Any of the a/d/s/ mini-speakers can be placed on a shelf or other solid surface. If the speakers are placed

on a shelf, put the supplied adhesive-backed felt pads on the bottom of the cabinets. The pads protect

the surface under the speakers and reduce the possibility of rattles or buzzes. The L210 and L310 may

also be used freestanding.

mounting the speakers

Before mounting the speakers in brackets, plan the mounting location and method very carefully. Follow

the speaker placement guidelines described in the instruction manual and decide on the mounting

locations. If you plan to hide the speaker wires behind the mounting surface, route the wires before you

mount the brackets. See the following section for information on wiring.

How the brackets should be fastened to the mounting surface depends on the structure and material

of the mounting surface. There are two typical situations. One is with the brackets attached to a

conventional wall constructed with drywall material over wood studs. The other situation is with the

brackets mounted to a wood cabinet or some other solid material. When the speakers are mounted on

drywall the plastic screw anchors will be used in conjunction with the screws. When the speakers are

mounted on a solid panel the screws anchors will not be needed. Driving the screws directly into the

solid panel will provide a strong enough mounting.

The L-series speaker system is supplied with brackets for horizontal or vertical mounting. Pick the

correct bracket for your application, and set the bracket in the installation location. Be sure it is

straight. Using the bracket as a template, mark the location of the two mounting screw holes. Set the

bracket aside. If the plastic anchors will be used drill the holes for them with a 1/4" bit. If only the self

tapping screws are used, drill pilot holes with a 1/8" bit. Push the plastic screw anchors, if they are

being used, into the holes drilled for them. NOTE: If the speakers are being mounted horizontally the

opening in the end of the mounting brackets should be oriented upward.

Drive the mounting screws through the bracket, into the holes, until they are firmly set. Connect the

wire to the speakers (see wiring tips in following section). Set the speakers in the mounting brackets,

placing a rubber washer between the speaker cabinet and the bracket on each side. Secure the cabinet

to the brackets with the threaded knobs, placing a second rubber washer around the threaded part of

each knob. Position the speaker as desired, and tighten the knobs.

wiring

Wire

Use two-conductor stranded-type, insulated wire to connect the speakers to the amplifier. “Lamp” wire

or “zip cord” works well. If you are running wiring within the walls, make sure that it complies with

your local building codes pertaining to low-voltage wiring. Use at least 16 gauge for runs of less than

50 feet. Use 14 gauge or larger wire for longer runs. The resistance of 18 gauge or smaller wire can

cause a bass response peak if used for more than a few feet.

Preparing the wire

Estimate the amount of wire needed. Allow enough extra wire so you can move the speakers if

necessary. Separate the conductors of each wire pair a few inches in from the end. Strip about 3/8”

insulation from each conductor. Be careful not to cut into the wire itself. Twist the strands of the

conductor together to avoid fraying. For outdoor use, terminate the wire with gold-plated pin-type

terminals and insulate the wire-to-pin connection with silicone filled heat-shrink tubing. Bare copper

wire can corrode and cause unreliable connection over time.

Polarity

The polarity - the positive/negative orientation of the connections - for every speaker-to-wire and wire-

to-amplifier connection must be the same so the speakers will be “in phase”. If the polarity of one

connection is reversed, bass output is reduced and stereo imaging is degraded. All wire is marked so

you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor.

The wire may have clear insulation with different color conductors (copper and silver). Decide which

conductor you will use for “positive” and which for “negative”. Then be consistent with every speaker-

to-wire and wire-to-amplifier connection.

Speaker input connectors

The speakers have color coded push-to-connect input terminals that accept virtually all types of speaker

wire. Push the back of the terminal to open the wire access hole. Put the stripped wire or pin terminal

into the hole and release the terminal.

Making the connections

Connect the positive conductor of one wire to the red input connector of one speaker and to the red

or “+” speaker output connector of the associated amplifier channel. Connect the negative conductor of

the wire to the black terminal of the speaker and to the black or “-” connector of the associated

amplifier channel. Repeat the procedure for the other channel. Be sure to follow exactly the same

connection procedure for both channels.

speaker protection

The speakers have a solid-state, fully automatic tweeter protector. This device reduces the power to the

tweeter when the speaker is operated at unsafe power levels. The protector resets itself when power

is reduced to a safe operating level. If high power operation causes the tweeter to stop playing, turn

down the volume control until normal sound resumes. Note: The tweeter protector provides a significant

level of protection. However it does not guarantee that the tweeter cannot be damaged. Always be

careful when operating the speakers at a high volume level.

maintenance

The drivers require no routine maintenance. Do not let anything touch the drivers. Do not vacuum clean

the drivers or front panels of the speakers. Some dust accumulation on the drivers is normal and does not

affect the sound in any way. Heavy dirt buildup may be carefully removed with a soft paintbrush if

necessary.

The enclosures of your a/d/s/ speakers require no maintenance other than dusting. Dust the speakers

with a dry or slightly damp cloth. To clean the grills, remove them from the speaker and vacuum them.

Do not vacuum the grille while they are on the speakers.

Most difficulties with high fidelity equipment result from loose or poor connections, bad

connecting cables or switches in the wrong positions.

No sound It is rare for a speaker to fail completely. When there is no sound, check all the speaker wire

connections and the setting of the amplifier’s tape monitor or speaker selector switch.

Dull or muted sound Operating the speakers at an unsafe power level activates the automatic tweeter

protector. Turn down the amplifier volume control and the protector will automatically restore signal to

the tweeter. Also check the amplifier’s tone controls or “high filter” switch.

Distorted Sound Distortion at moderate levels can be caused by loose connections, or stray wire strands

shorting out adjacent wires at the amplifier or speaker terminals. If you hear distortion or any type of

buzzing or rattling sound from an individual driver, contact your a/d/s/ dealer. Distortion at high levels

is the result of either reaching the power limit of the amplifier or of the speaker. Turn down the volume

to prevent damage.

Noise or Hum Continuous background noise or hum are always from the electronic equipment and not

from the speakers.
